We are using pic16f676, mikrocpro for pic and pickit2v2.61 writer. The problem is that for the same program of a timer on the same hardware, we are getting different timing values for different ICs, i.e. for 1 IC, it is 1 minute, for other it is 1 minute 3 sec. etc. We have changed the osccal value in writer, but it doesn't accept the change.
Also, in the code, if we change osccal value, then it changes the timing value but the difference still remains for different IC. Kindly help us.
Thank you.
